Abstract
A piezoresponse technique based on scanning force microscopy (SFM) has been used for studying domain structure in ferroelectric thin films. Studies were performed on Pb(Zr-x,Ti-1-x)O-3(PZT) thin films produced by a sol-gel method. The piezoresponse images of the PZT films were ta ken before and after inducing polarization in the films by applying a direct current voltage between the bottom electrode and the SFM tip. P olarization induced patterns were written with 20 V pulses and subsequ ently imaged by the SFM piezoresponse technique. The effect of the fil m structure on the imaging resolution of domains is discussed. (C) 199 6 American Vacuum Society.
